The problem with -Wl, is that nothing gets put into the .la file which is
what Matthias needs (I think).
Maybe libtool should be made to include the -Wl, stuff in the dependency_libs
in the .la file.

This description is not strictly correct. -Wl, gets interpretted by libtool
into the equivalent compiler and linker options. When you use a compiler to
link it should get the compiler options and if you use a linker to link it
should get the linker options. So, I don't believe a compiler will ever see
-R.

ps. this should come with the disclaimer that libtool is an enigma at the
best of times and so it could all be wrong. :)
